COAL OR ORE BU CKETflOR CARRIER.

SPECIFICATION forming part of Letters Patent N0. 311,789, dated February 3, 1885.

Application filed Der-ember 12, 184.

useful Improvements in Goal or Ore Buckets; and I do declare the following to be a full,

- 'clear, .and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification,

My invention relates to buckets or carriers for coal, ore, or the like; and the novelty consists in the construction, arrangement, and adaptation of parts, as will be more fully hereinafter set forth, and specifically pointed out in the'claiins.

For convenience, I will illustrate the invention as applied to a dumping-buckeaadapted to be raised by any ordinary power upon a swinging crane; but the features of importance will beunderstood to serve with equal success in other relations.

My bucket is preferably made of sheet metal,

and has a bottom inclining in opposite directions from a central line. The bucket has hinged doors upon opposite'sides, the hinges being uppermost, and fromeach door curved links extend inward past each other, and are secured to cross-bars upon a rock-shaft in such a manner that the points of connection, when the doors are closed, are in a position past the center of'motion of the rock-shaft. This position firmly locks the doors in place and avoids thenecessity of any securing devices whatever, while the greater the pressure upon the doors the more firmly will they be lockedfuntil a lever is operated to force the pivots upon the y can per cent.

other side of the center, when the'pressure upon the doors will open them. I propose that this lever shall be operated from a distance, as by the engineer, and thus avoid the necessity of employing a man as a dumper.

Aconsiderablepercenta ge ofloss is sustained in handling'coal or ore, due to the breaking up of the material. This'loss, where turningbuckets are used, has been estimated at eight This is due to the fact that the necessary room for turning the bucket gives (No model.)

more or less fall to the contents-say six or seven feet.

In my construction the bucket may be low ered as far as desired, and by the proper manipulation of the lever the contents maybe easily deposited where required without any appreciable shock or damage.

The invention is illustrated in the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a vertical crosssec-tion; Fig. 2, an elevation of oneend, showing the operatinglever; Fig. 3, an'elevation of the opposite end; and Fig. 4, a side elevation, broken away to shbw internal parts.

Referring to the drawings, in which similar letters of reference indicate likepartsin all the figures, A designates the body of the bucket, having a'bottom, B, incliningin opposite directions from a central line, b, as shown. These parts are preferably made of proper metal, and the bucket is preferably rectangular. Upon each side is formed, from a point near the vertical center downward, an eXit-aperture,.C, controlled by adoor, D, hinged above, as shown at d, and so arranged as to completely close the aperture 0 by its gravity. Passing through the ends, and under and along the line b, is a rock-shaft, E, and rigid with this rock-shaft,

and arranged upon the ends thereof which project outside the ends of the bucket, are two crossarms, F, and to these arms are loosely pivoted curved links f and f. Each link f is pivoted at one end to lug d upon one door, and extends past the rock-shaft E, and has its opposite end loosely pivoted to the end of the cross-arm, while the link f serves similarly between the opposite door and the other end of the cross-arms.

By reason of the curvatures seen at f in each of the links the pivotal points marked a: w are carried beyond the center of motion of the rock-shaft before the links come into contact therewith, and in this feature lies an important function. The parts mentioned-that is to say, the doors, rock-shaft, cross-arms, and links-are so proportioned to each other that when the doors are squarely closed the concave sides of the linkslie in contact with the rock-shaft above or below. Hence any pressdanger of the fastening jarring loose This ure upon the doors from the inside serves to lock them more securely.

I provide 'upon one end'ot' the bucket a le ver, G, which lies in a plane parallel with that of the cross-arms F, and it is made rigid with the rock-shaft. A rope, as H, may be secured to said lever and passed over a pulley, h, or through the eye of the bail I, or elsewhere, and, running back to the engineer, may be employed to unlock the doors. This unlocking is very easily accomplished. A slight force will serveto oscillate the rock-shaft until the pivots'm w pass-the center, when the pressure upon the doors will complete the operation. After the contents have been de posited the doors, by their gravity, close, and the weight of the lever throws the points x as past the center, ready for another charge.

This application is made with full knowledge of a dumping-ear shown in Pate'nt'No. 26,460, of 1 859. I desireto fully recognize the state of the art 'as evidenced in said patent. The bottom, the receptacle, and doors in that patent served a similar purpose; but the connecting links never went past the center of motion of the rock-shaft, and there was always a danger was so apparent that an independent I catch to lock the lever wasemployed.

In my device I utilize the gravity of contents being carried to lock the doors.

What I claim as new is- 1. In a coal-carrier, substantially as de-- connecting each door to pivots beyond the shaft and past the axis of its motion, whereby the weight of the contents will increase the. security of thelock, and a lever, as G, adapted tooscillate the rock-shaft to release the lock, as set forth.

2. The coal-bucket described, consisting of the body A, having exit-apertures 0, double inclined bottom B, doors D, and rockshaft E, having cross-arms F, the links ff, curved, as seen at)", and connecting thelugs dupon the doors with the pivots at 00 upon the cross-arms, the lever G, rigid with the rock-shaft, and the rope H, adapted to inanipulatethe'locking devices from a distance, as and for the purposes set forth.

In testimony whereof I alfit my signature in presence of two witnesses. 7 v
